摘要

针对玛湖砾岩油田采用水平井段内多簇+暂堵压裂技术压后产量未达预期问题,选择MaHW26X试验井中第2—6段开展不同泵注参数冲蚀试验,利用射孔成像监测孔眼磨蚀程度,进而分析各簇裂缝起裂均匀程度及支撑剂进入情况。研究表明：76.7%的射孔孔眼有支撑剂进入,大部分射孔簇进入的支撑剂量有限,支撑剂的分布主要集中在个别簇中。试验井中第4段支撑剂分布较为均匀,段内各簇裂缝起裂的均匀程度较高;第2、3、5、6段支撑剂分布不均匀,段内各簇裂缝起裂的均匀程度较低。个别近跟端射孔簇的支撑剂进入量占该段的70%以上,在加入暂堵剂后并未促进水力裂缝均衡起裂。支撑剂进入量与孔眼磨蚀程度呈正相关关系,试验井孔眼磨蚀程度为15%~352%,平均值为74.5%,远大于北美页岩储集层部分水平井。采用180°相位角（水平方向）射孔可减小孔眼磨蚀的相位倾向,促进孔眼均匀磨蚀与进液。研究结果可为优化泵注程序、减轻炮眼冲蚀、提高暂堵成功率提供依据。

Abstract

To solve the problem that the production of Mahu conglomerate reservoir is not up to expectation after the multi-cluster plus temporary plugging fracturing technology is applied in horizontal wells, stages 2-6 in the test well MaHW6285 are selected to carry out erosion tests with different pumping parameters. The downhole video imaging technology is used to monitor the degree of perforations erosion, and then the fracture initiation and proppant distribution of each cluster are analyzed. The results showed that proppant entered 76.7% of the perforations. The proppant was mainly distributed in a few perforation clusters, and the amount of proppant entered in most of the clusters was limited. The proppant distribution in stage 4 was relatively uniform, and the fracture initiation of each cluster in the stage is more uniform. The proppant distribution in stages 2, 3, 5, and 6 was significantly uneven, and the uniform degree of fracture initiation in each cluster is low. More than 70% of the proppant dose in the stage entered clusters near the heel end, so the addition of diverters did not promote the uniform initiation of hydraulic fractures. There was a positive correlation between the amount of proppant added and the degree of perforations erosion, and the degree of perforations erosion ranged from 15% to 352%, with an average value of 74.5%, which was far higher than the statistical results of shale reservoir tests in North America. The use of 180° phase perforation (horizontal direction) can reduce the “Phase Bias” of perforations erosion, promote uniform perforations erosion and fluid inflow. The research results provide the basis for optimizing the pumping procedure, reducing the perforation erosion and improving the success rate of diversion.

Key words： tight conglomerate; temporary plugging fracturing; perforation erosion; fracture initiation; downhole video imaging technology; Junggar Basin; Mahu sag
